evaluate 3%2F4%2B2%281%2F5%29%5E2
you did 1%2F5 first 1%2F25 and that is correct

3%2F4%2B2%281%2F25%29.........now you have to multiply %281%2F25%29 by 2 or (as a fraction)2%2F1

so, to multiply %282%2F1%29%2A%281%2F25%29 you need to multiply nominator by nominator and denominator by denominator

%282%2A1%29%2F%281%2A25%29=2%2F25........now plug it in your 3%2F4%2B2%281%2F25%29

3%2F4%2B2%2F25.........common denominator for 4 and 25 is

100, so you will have

%283%2A25%29%2F%284%2A25%29%2B%282%2A4%29%2F%284%2A25%29

75%2F100%2B8%2F100

83%2F100
